I've viewed the first (of 3) episodes and really enjoyed it. It's a 'grown up' production, beautifully filmed and with a pace and editorial that engages you from the start. The acting is superb, particularly Michael Sheen as Price Andrew. It's a substantial piece of work covering the before, during and after the interview and I very much look forward to watching the 2 remaining episodes. It's fun too!
PS - the reviewer ExiledRoyal notes that as the production is shot in letter box format, the top and bottom black bars are frustrating. The reviewer might like to adjust the settings on their television so that the set can adjust to the format. I get a full screen with no image miss and no black bars.
